The previous sections have presented the first experimental proof-of-concept on background suppression using an i-TED prototype with limited hardware characteristics and position-reconstruction algorithms compared to the final 4\(\pi \)  i-TED detector, hereafter simply referred to as i-TED. The latter will be composed of four individual Compton Imaging modules, each of the them consisting on two position sensitive detection layers based on monolithic LaCl\(_{3}\) (Ce) crystals. Each scintillator is optically coupled to a SiPM, which features
a segmentation of 8x8 pixels. The S plane is composed of a single 50x50x10 mm\(^{3}\)  crystal, while the A plane consists of an array of four crystals, each of them with a size of 50x50x25 mm\(^{3}\) . A detailed description of the first demonstrator of an i-TED module can be found in Ref. [1]}.
